, Be it known that I, TiLMON J; (lannoon,

I a citizen o f tlie United States; residing .at

Monroe, in the. p arish of Ouachita and State of Loulsian'a have invented fa; new useful. Wrench, of which the following ,is a

specification.- c, -The device-formingthe' subject matter of this application is a Wrench adapted "tobe' employed in thema'nipulation'of a nut having a -lock"of t sp.ecii icform,1as hereinafter described;

' In the wrench ferming thesnbject matter v of this application, fa releasing member is provided whereby a locking latch upon the nut :is moved into anrino'perative position. I One object of the-present invention is to provide a releasing "meinber'- of novel form and -to provide, novel. means for 4 controlling,

and actuating" the releasing member.

If; however,/ the resilient arm 4 is elevated so that the finger 5 no longer is engaged with the teeth 7, then the nut 2+3 may be threaded oflijthe spindle 1. A raising of-the arm. 4 may be brought about: by thrusting a recontain patentable 'features,".such {features Passing to av description of the wrench which alone canbe claimed in this applica- Q tiOm-the-fs'ame isshown as comprising a handle 8 which if desired; may be provided 9 for handling nuts of diflerentsizes, the ele-.

.- secured to the shank 3 ofthe nut, the outer may ;'beembodied in a separate application.

-.a t"i ts free end with theusual appurtenances Obviously, if desired, the parts indicated a [The handle 8.."s offset to form a laterally projecting arm 10 terminating in a nut receiving head 11 having a polygonal opening 12. One Wall of the" head 11 is provided with a notch 2%, the function of which is to receive the arm 4 when the Head 11 is slipped onto the Wrench shank 30f the nut. v I -In the, arm: 10 there is formed a guide referablyin the form of 'a hole 14 and- 111 in the form of-a' rod, the releasing member end of the releasing member is beveled as shown at 17, so that the forward end of thereleasing member may pass readily beneath the resilient arm 4 toefl'ect a raising thereof,

- the forward end of .the releasing member ordinarily being received in the seat 6.

A means is provided for-advancing and retracting the releasing member 15, and YVlth. this end in view, the releasing member is provided adjacent its rear end with an eccentric strap 18 surrounding an eccentric 19. Attached to the eccentric 19 is an ac 'tuatmg element 21 preferably in the form of a lever or handle, adapted to move above the handle portion 8 of the wrench. A

pivot element 22 passes through the eccentric 19 andis carried'by the handle 8.

At its free end, the handle portion 21 of the eccentric is provided with a lateral projection 23 adapted toengage the upper edge of the handle 8 under circumstances which will be pointed out hereinafter.

'VVhen the releasing member 15 is in the retracted position .shown in Fig. 1, the handle portion 21 of the eccentric l9 is rearwardly extended and the projection 23 engages the'handle 8. Thus, the retracting movement of the releasing member 15 is limited. With the parts thus positioned, the

head 11 'of the wrench is slipped over the shank 8 of the nut 2. Then, the handle 21 of the eccentric is swung over in the direction of the arrow A in Fig. 1 until the pro .jection 23 engages the upper edge of the handle Sas is shown in Fig. 2. By this operation, through the instrumentality of the eccentric 19 and the strap 18, the releasing member 15 is advanced until its beveled end 17 passes underneaththe arm 4t and elevates the same, so that the finger 5 no longer is engaged with the axle 1; Thereupon, the nut Q'may'be rotated, in the usual manner, to tighten or to loosen the same. I When the handle 21- of the eccentric l9 isrestored to the position shown in Fig. 1, the forward end of the releasing member 15 is in re-.

tracted position with respect to thearm 4, the arm 4 resumes the position shown in Fig.

'4', and the head'll of the wrench may be slipped readily off of the shankportion 3 of the] nut.

Having thus described the invention, what is claimed is 1. In a device of the class described, a wrench comprising a handle, a laterally olfset arm projecting from the handle, and 'a' head on the arm, the' head being provided with an opening, and being disposed ap proximately parallel to the arm; a longitudinally movable releasing member one end of which moves close to one edge of the opening and approximately parallel thereto,

tric pivoted to'the handle and coacting with the strap. I

'3. In a device of the class descr1bed,a wrench comprising a handle and a nut rethe releasing member being ofl'set intermediceiving head; a releasing member movable longitudinally of the handle-and comprising an eccentric strap; an eccentric pivoted on the handle and coacting with the strap, the eccentric comprisinga lateral projection coacting at different times with spaced parts of the-wrench to define the advanced and retracted positions of the releasing member.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence-of two witnesses.
